It is well known that after slaughter of pigs, cattle, sheep and other livestock and poultry, proper cooling and lowering of carcass and muscle temperature can reduce the occurrence of PSE meat. Studies by foreign experts such as Kauffman show that the use of cooling temperature below 0 ℃ reduces the occurrence of PSE meat, but too fast cooling and too low cooling temperature (below - 30 ℃) reduce the tenderness of pork. Generally, rapid cooling at - 20 ℃ for 2-3 hours, followed by conventional cooling methods, will reduce the occurrence of PSE meat without affecting the tenderness of pork
Effect of humidity on the cooling process Temperature of acid discharging storage, pre cooling storage, thawing storage and fresh-keeping storage can be easily reached and controlled, but humidity is constantly changing during the cooling process, * * * can be reduced to 70%, which has a great impact on the carcass. During cooling, it is necessary to use the air cooler to reduce the temperature. When the warehouse temperature is 0~4, the temperature in or near the air cooler is below zero. When the air in the cold storage circulates through the fan, the water vapor in the air is condensed into "frost" and attached to the fan surface, resulting in the reduction of air humidity. As the air humidity decreases, the moisture in the carcass will continuously evaporate. The lower the humidity, the faster the evaporation, and the greater the weight loss
Why should a humidifier be installed in the acid drain tank? The humidity requirement of the acid discharge tank is relatively high, and it is difficult to reach this humidity standard in the tank generally; Therefore, it is necessary to install a special humidifier for the acid drain tank according to its actual needs to improve the humidity in the tank, which can achieve a very good humidification effect:
◎ Keep the color, moisture and nutrient content of various livestock and poultry meat
◎ Increase the humidity content and inhibit the evaporation of various livestock and poultry meat
◎ The acid drainage storehouse of livestock and poultry meat products can moisturize, which can reduce the dry loss
Next, take the experiment of Changchun Haoyue Company as an example to understand the use effect of the special humidifier for the lower acid tank:
Haoyue Group is the leading enterprise of the Ministry of Agriculture, slaughtering 200000 beef cattle annually. There are 7 acid discharge warehouses, each of which can hold 288 heads. In the experimental environment, the company's No. 4 acid discharge warehouse has a size of 8mx27mx 6m=1296m3, a temperature of 0-4 ℃, and a humidity of 85% - 95% RH. Two sets_ The humidifier of the acid discharge tank is placed directly above the center of the cold storage for spray humidification
The dry consumption rate decreases. The reduction of dry consumption rate means the increase of carcass weight and its economic benefit. If the dry consumption rate is reduced by 0.1423%, if the carcass weight of a cow is 520kg, the dry consumption will be reduced by 0.73,996kg. If the annual slaughter volume is calculated as 10,000 cows, the weight loss will be reduced by 73,996kg, and the economic benefits will be considerable
_ The humidifier specially used for the acid discharge warehouse and ZS series high humidity resistant spray humidifier products adopt the principle of ultrasonic high-frequency oscillation, so as to achieve the goal of uniform humidification; For humidifiers of other humidification methods, it has the remarkable advantages of [fine atomized particles], [low energy consumption], [high atomization energy efficiency] and [fast humidification speed]; It can not only uniformly humidify large space, but also compensate local humidity in special space, with high flexibility. Welcome to inquire about the details of the humidifier and spray moisturizing to reduce the dry consumption of the acid drainage tank
